6

As soon as you see the logo, you will need to hit either F1, F2, F6, F10, or Del to enter the BIOS menu—the key you need to press should appear quickly on the screen (look for «Press X to enter setup»).
-
8
Click Restart. Your PC will now reboot into the BIOS/UEFI, which is where you’ll tell your PC you want to boot from your USB flash drive.
-

Find the Boot menu. Every manufacturer has a different BIOS/UEFI setup, so you may have to browse around to find a menu called Boot, Boot Order, or Boot Options. You’ll know you’re in the right place once you see a list of different types of drives (such as optical drive, removable drive, USB drive, etc.).
- If you’re using a Lenovo PC, for example, you’ll select the Boot tab at the top.
- You may have to select a menu called Advanced, Storage, or System Configuration to find the Boot or Boot order menu.[1]
-
10
Change the boot order. This area is going to look different depending on the manufacturer. Your goal is to make the device that’s called something like «USB drive» or «Removable Drive» the first item in the boot order.
- If you don’t see an option to change the order of the drives, you may just need to switch on a setting that enables «USB Boot» or similar.
-
11
Save and exit. You can usually do this by selecting a tab or option called Save & Exit, or by pressing F10. Once you confirm and exit, your PC will reboot from the USB drive.
- Be sure to remove the flash drive when you’re done using it. Otherwise your PC will try to boot from it the next time you have to reboot.

Question
What can cause my computer to display multiple colors after installing Windows 7?
If you’re booting from a copy of Windows 7 on a USB drive, the most likely culprits are a corrupted copy of Windows, which just requires a reinstall, or damage done to the USB, which may be present on either the drive or the computer’s port itself. Or the monitor may just be having some issues of its own. If you get these colors when doing hardware intensive tasks like gaming, exporting video files or any other GPU-intensive tasks, the driver may be crashing which can be caused system errors or by overheating of the card.

It’s possible to boot Windows from a USB drive, as long as you follow the right approach. Here are the best ways to boot from USB on Windows 10.
So you want to boot Windows 10 from a USB flash drive?
Maybe you need to install a new version of Windows 10, or you’re looking to troubleshoot some problems. Whatever the reason, by the end of this article, you’ll be comfortable with booting your PC from a USB flash drive.
So let’s get started with booting your Windows from a USB drive.
How to Boot Windows 10 from a USB Flash Drive
To run Windows from a USB stick, you’ll need a bootable USB drive. But what’s a bootable USB anyway?
Simply put, a bootable USB is a USB drive that contains an ISO version of an operating system. An ISO file is a clone of disc files (DVD or a CD). In our case, the USB flash drive will contain the ISO version of the Windows 10 operating system.
So the first thing you need to take care of before you boot your Windows from a USB drive is to make your USB drive bootable. But how do you do that?
While there are plenty of methods to create a bootable USB drive, the easiest one is to use the Windows 10 Media Creation Tool. It’s a free tool from Microsoft that lets you download the ISO image of a Windows installation file onto a DVD or flash drive for installation.
- To get started, download and launch the application. Then select the Create installation media (USB flash drive, DVD, or ISO file) for another PC, and click on Next.
- From there, set your preferred language, Windows edition, and architecture. We suggest that you stick with the Use the recommended method for this PC radio box and let the tool take care of everything. Then, click on Next.
- Now, select the USB flash drive option to boot Windows from a USB drive, and click on Next.
The Windows 10 installation on your USB will begin. Depending on the speed of your internet connection, the whole process could take a while.
Boot From the Windows 10 USB Driver
When your bootable USB drive is ready, you need to restart your PC with your bootable USB drive in it. After you’ve plugged your USB into the computer, here’s what you need to do next:
Startup your computer and repeatedly press the BIOS/ UEFI access key. The key could be ESC, F1, F2, F8, or F10, but it varies between manufacturers.
After successfully pressing the key, you’ll reach the BIOS. In the BIOS, ensure that the USB is set as the main boot device. This is so that your PC can boot directly from the USB flash drive instead of booting from your computer’s hard drive.
At last, save the changes and restart your computer.
If everything was done right, your PC will start from the bootable USB drive containing the Windows files. You are free to use it however you please.

How to boot from USB using your Windows computer’s startup system
If the Windows 10 boot method doesn’t work, it might be because your PC’s BIOS (basic input/output system) doesn’t support it. You can still boot from the USB drive, though you will need to tweak the BIOS settings.
Unfortunately, every BIOS screen is configured differently, so you will need to explore the options for yourself.
1. Shut off your computer.
2. Turn it back on and press the key indicated briefly on the startup screen to enter your BIOS Setup. It’s usually Escape, F1, F2, F8, F11, or F12. If no such screen appears, your BIOS may be set to «fast boot» mode, so you will need to experiment with different keys at bootup, before the Windows screen appears. For more information, you should consult the documentation that came with your PC.
3. In the boot menu, look for the boot order controls and move the USB drive to the top of the list.
4. Save your settings and restart the computer with the USB key installed.
